Singer-songwriter Joe Ely was in the middle of his set with Alejandro Escovedo at the Austin Music Hall, when he called his good friend Springsteen onto the stage.
"We need one more guitar player," Ely told those in attendance, reports Rolling Stone.
Springsteen provided back-up for the remainder of Ely and Escovedo's set and chimed in on vocals for 'Always a Friend' and the Rolling Stones' hit 'Beast of Burden'.
The Austin Music Awards are held annually to coincide with the South by Southwest music and technology festival.
Springsteen is in Austin to give the South by Southwest keynote address tonight (Thursday) at the Austin Convention Centre.
